Bullet drop question

my worst group of three was 1.5" my best .75" I know I should have quit sooner as I was getting tired and frustrated.

I've hunted a long time and have never needed to shoot over 200 yards, at deer and moose. My elk hunting buds are telling me I need to be ready to shoot 600 or more so I either need to get this figured out or do what I'm most comfortable with ... shoot ethically within my comfort range.

Since it's to late to send my scope in to Leupold for custom turrets I ordered a turret from Stoney Point to see if this could help, any views on these?

I've used em in the past, they are by no means the right tool for the job, but in a pinch and used with reason they can get you by. sort of like a bandaid

Keep in mind the animals we shoot for food and display are not bullet proof. Contrary to popular belief, they bleed and die just like they did a hundred years ago. Being competent with a given rifle is far more important than impressive ballistics and poor shootability. High velocity misses never put a steak in the freezer.
